Average alcohol withdrawal scoring and average benzodiazepine dose (mg) versus initiation of dexmedetomidine therapy. Alcohol withdrawal scores were averaged each hour for all patients with complete data available (n = 11) as was average hourly benzodiazepine dose in mg (n = 17). Measurements were recorded from 24 h prior to dexmedetomidine therapy through the first 24 h on dexmedetomidine. Negative numbers represent data prior to the initiation of the study drug and the time point 0 represents the initiation of dexmedetomidine. Error bars reflect the standard error around each mean value.
